| The moats have since filled in, but the interferometric radar is so subtle that it detects the change in the height of the former banks. |
|
| A separate laser provided interferometric information to measure the field of the signal. |
|
| This technique is closely related to a previous interferometric method for measuring the optical phase-space distribution of a light field. |
|
| This method combines multiple white light interferometric sensors and advanced image processing. |
|
| Now, he says, there are laser and interferometric techniques that make it possible to measure all of these things at once. |
